REFRIGERATOR-DOOR.

To all whom it may concern:

Be it known that I, GEBHARD 0. Bonus, a citizen of the United States,residin at St. Paul, in the county of Ramsey and tate of Minnesota, 1340University avenue, St. Paul, Minnesota, have invented certain new anduseful Improvements in Refrigerator- Doors, of which the following is aspecification.

My invention relates to improvements in doors and more particularly tothose doors adapted for use on refrigerators where the entire outside isof vitreous material, its object being to provide means for fasteningthe outer enameled sheathing to the inner portion of the door withoutrunning screws or other fastening means through the sheathing.

In the accompanying drawings forming part of this specification Figure 1is a section through my improved door;

Fig. 2 is a plan view as taken on line 2-2 of Fig. 1;

Fig. 3 is a section taken on line 3-3 of Fig. 2; and

Fig. 4 is a detail view illustrating a modified construction.

Referring to the drawings, A represents a refrigerator door and 2 anenameled late or sheat ing for the door. The door is pre rably coveredupon its inner side with an enameled lining plate 3. The frame work 4,preferably of wood, is constructed in any desired manner and preferablyhas the usual insulating layers 5 between the outer and inner plates 2and 3.

In order to support the outer covering plate 2 upon the frame workwithout running screws or other securing means through the plate, llprovide a plurality of strips 6 with mitered corners so that they maybe' fitted together, as shown in Fig. 2, and form a backing for theouter sheathing plate 2. The outer sheathing-plate is heldlocked uponthe strips 6 through the medium of ribs or flanges 7 extendinglongitudinally along the outer edges of'said strips, the free edges 8 ofthe plate 2 extendmg upwardly and inwardly whereby to fit oversaidflanges 7, as illustrated best in Fig. 1. In order that the strips 6 maybe placed Specification of Letters Patent. 7 Patented Apr. 23, llllllfio Application filed September 4, 1917. Serial No. 189,484.

'in position interlocking with the edges of 6 were constructed with aflange which would fit under the inturned edge of the sheathing, itwould be impossible to get all the strips in the position shown and inorder to overcome this difliculty, I either leave the flange off of onemember of the sectional strip or, as shown in Fig. 3, make the flangesmall enough so as not to cause difficulty in the assembling of theparts. a

I may, however, out one of the strips into three sections, asillustrated inFig. 4:, and where I (.0 this, I am able to form the outeredges of all of the strip sections with a full sized flange 7. Inutilizing the form of strip, shown in Fig. 4, the two ends may be shovedendwise into position and the cen tral pieces thenshoved in between theends.

When the strips are thus fitted to the back of the sheathing plate 2,the frame work will be placed thereon and secured thereto,

as shown in Fig. 1. This will hold the strips in positioninterlockingwith the edge of the sheathing plate. It is thus impossible to separatethe sheathing plate from the door when the parts are assembled and theframe work secured to the strips 6. With the frame work disconnectedfrom the strips 6, the strips are easily forced into locking engagementwith the edge of the sheathing plate or out of engagement therewith. Ithus by the features of construction shown secure a sheet metal covereddoor, whlch, by

reason of needing no screws or other means 2. A door of the classdescribed including 7 a metal covering plate formed with inturned edges,backing strips interlocking with said edges and an inner door portionsecured to said strips and holding the same in looking engagement withsaid plate.

3. A door of the class described including In testimony whereof I afiixmy signature an outer cover-mg plate formed with inin presence of twovgitnesses. turned edges, backing strips formed with flanges fittedunder sald edges and an inner I GEBHARD BOHN 5 door portion secured tosaid backing strips Witnesses:

and holding the same in norfnal position for A. R. TAYLOR,

the purpose set forth. P. O. SCHNEIDLER.
